LIFE-BOAT.

SPECIFICATION forming part of Letters Patent No. 611,021, dated September 20, 1898. Application filed December 22, 1897. Serial No- 663,023. (No model.)

To all whom it may concern.-

Be it known that I, ANDREW F. PENDLE- TON, a citizen of the United States of America, and a resident of Franklin, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Attachments for Life-Boats, of which the following is a specification.

My invention relates to an improvement in air-chambers designed to be attached to the sides of life-boats or vessels to prevent their being capsized; and the object of the invention is to provide a chamber which while serving the above purpose may also be used as a receptacle for Valuable papers or the like, so that in case the boat should be come wrecked and the chamber detached from the boat the papers will be preserved from harm and also will be kept dry at all times.

To this end the invention consists in an air-chamber adapted to be secured to the side of the boat and made in two parts adapted to be separated to receive the papers or other articles and to be placed together again to form a single water-tight compartment.

The invention also consists in the particular construction hereinafter described, and particularly pointed out in the claims.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a boat, showing the air-chamber attached. Fig. 3 is a cross-section of the same. Fig. 2 is a detail view illustrating the method of securing the two sections of the chamber together.

Referring more particularly to the drawings, A A represent the two sections of the air-chamber, which are preferably of the shape shown and may be made of leather or canvas or any suitable material which has been made air-tight. One or both of these sections may be provided with an air-valve by means of which it may be inflated, and the chamber may be secured to the side of the boat by suitable straps B or in any desired manner, the boat being indicated at O. In order to secure the two sections together, I place within one of the sections a wooden plug or short which pass a bolt for drawing the band tightly around the overlapping ends of the section and clamping them tightly against the plug or cylinder.

In order to facilitate the drawing of the section A over the section A, I prefer to provide straps a, by means of which the section may be easily drawn to its place.

In case only one filling-valve is used it is necessary to provide a suitable opening or passage through the plug to permit the air to flow from one section to the other.

Having thus described my invention, what I claim is- 1. An attachment for life-boats comprising an air-tight chamber made in two separable flexible parts with means for securing the parts together, substantially as described.

2. An attachment for life-boats comprising the sections A and A having overlapping ends, the plug or cylinder within said ends and the clamping-ring surrounding the same, substantially as described.

3. An attachment for life-boats comprising the plug or cylinder, the section A overlapping the plug, the section A overlapping the first section and having pulling-straps and the clamping-band surrounding said parts, substantially as described. I

4. An attachment for life-boats comprising two overlapping sections, a plug or cylinder within the same at the point where the sections overlap, a clamping-band for clamping the sections to the plug, and a filling-valve in one of the sections, the said plug or cylinder having the passage forming a communication between the two sections, substantially as described.
